Word of caution: this is a personal site. Though it is on Internet and not protected against public viewing, it is not specifically designed to satisfy everybody, who could browse to this place. It is designed for my friends and colleagues. Large
parts of this site (usually marked with sign or "Русский" tag) are
in Russian. Though I plan to limit this site by these two languages, you still may occasionally encounter fragments in German, French, Latin, Greek, or Hebrew.
